Attic Ventilation Systems
Pond Roofing & Exteriors is your one stop shop for “everything roofing.” We install ridge vents, eave vents and attic fans to save you seasonal heating and cooling expenses and to protect the integrity of your home roofing system. Ventilation is important for preventing excess heat and moisture build-up in your attic, thus lowering the chance of mold growth in your attic and premature deterioration of your plywood and shingles.
The Importance of Ventilation
A roof ventilation system (combined with adequate attic insulation) prevents heat and moisture build-up in the attic. During the summer, trapped heat in the attic can bake your plywood and shingles from the inside while the sun beats them from the outside. Excessive attic heat damages roofing components and reduces shingle life.
During winter months, proper roof ventilation will help draw out excess moisture rising from the home into the attic, which if trapped, can cause mildew, mold and promote dry rot of decking. Poor attic ventilation in the winter also creates uneven roof temperatures. Consequently, melting and freezing snow can form ice dams which may block water from draining off the roof.
Natural Ventilation: Ridge Vent with Soffit Vents
Stay green and save energy by combining soffit vents (intake vents placed at the underside of the eave) with ridge ventilation (outlet vents at the peak of the roof).
As the wind flows across the roof top, a natural convection effect draws hot air out while pulling in cooler air. Natural or passive ventilation is considered to be the most efficient and sustainable method of expelling heat and moisture from the attic. A good roof ventilation system also promotes air circulation and a healthy environment inside the home.
AirVent Ventilation systems are among our favorite products. This video shows how the AirVent ShingleVent II ridge vent stacks up against its competition.
Motorized Ventilation: Attic Fan with Soffit Vents
An electric fan can be mounted near the top of the roof in combination with intake vents. We do not recommend using a motorized fan if the roof has existing ridge vents as this can counteract proper air circulation. Pond installs temperature- and humidity-controlled attic fans to keep hot, moist air circulating.
